not new. we have had armed security at schools and universities before, and it just hasn't been effective. at columbine, at virginia tech, most notably, ft. hood, the most protected place on earth, almost, you had a complete outrage and massacre there. just having armed people around isn't necessarily the answer. i read a very convincing argument against it today, for example, with somebody saying you have these people, they get trained. they're armed. and they're concerned, not quite sure what they're looking for, and they get an odd looking character turns up. you could end up with all sorts of really unfortunate incidents. how do you kind of regulate that? >> certainly, you need to look beyond simply a trained, armed presence. the training is critically important in a sensitive environment. i think we ought to have more standardized training and enhanced training for anyone who is a protective person at a school. but secondly, right now, we have about one third of the schools that have an armed presence.
